Powered by a 12-cylinder, turbocharged, 2,000-hp 251-series prime mover, the C420’s direct competitor in 1963 was the EMD GP18. In fact, EMD did not offer a 12-cylinder, 2,000-hp prime mover until the GP39 model was produced in 1969. The shorter 12-cylinder engine block allowed the C420 to have its distinctive set-back cab and extended short hood.
The first road to purchase the C420 was the Lehigh & Hudson River, with its first two units built in 1963. The largest fleet was purchased by the Long Island Railroad, with 30 units built between 1963 and 1968. All were equipped with a high short hood which housed a steam generator for passenger service. Over time, the largest fleet of C420s was amassed by the Louisville & Nashville. While only 26 units were purchased new, their total fleet grew to well over 60 units through mergers and acquisitions. The C420 can still be found in daily service today in the US. Currently the largest fleet of C420s is operated by the Arkansas & Missouri Railroad.

Analog (DC) Operation
- The LokSound Select Dual-Mode decoder allows your Atlas Gold Series locomotive to be used on DC as well as on DCC layouts.
- Please note that the Atlas Quantum Engineer will NOT operate an Atlas Gold Series locomotive equipped with a LokSound Select decoder on an analog (DC) layout. However, the sound and lighting functions of the LokSound Select decoder in the Atlas Gold Series C424/425 locomotive can be controlled by an easy-to-use basic DCC system
- Also note that on a DC-powered layout, a DCC and sound equipped locomotive (such as the Atlas Gold Series C424/425) CANNOT be consisted with another locomotive that does not also have both DCC and sound. (This statement does NOT apply to DCC-equipped locomotives operating on a DCC layout.)
- Over 20 sound effects are available, including engine start-up and shutdown, prime mover sounds through all eight notches, bell, air horn, air compressor, dynamic brakes and more.
- There are 16 user-selectable horns, 2 user-selectable bells, and 2 user-selectable synchronized brake squeals.
